Hi all,

My 2009 X150 started leaking slightly and over a couple of days deteriorated.

Not too obvious from where the coolant was leaking due to dispersion, but attaching a pressure tester showed a very small spray coming from a hose where it is attached to a manifold toward the top of the front of the engine, behind the top belt pulley. Very hard to see directly, so I assume that some disassembly will be required.

My question is - what part is this part exactly? ...and is this part of a more substantial hose structure that should be replaced?

It appears to be connected at the visible end to the smaller port on the thermostat housing shown in the diagram also below.

Any guidance would be greatly appreciated!

Cheers! Phil

Here is the photo of the source of the leak (left hose in this picture and where it attaches with the hose clamp.


leaking from this joint - the hose on the left side is the culprit.
